FIELD: power industry.
SUBSTANCE: in spaceship with nuclear power plant, which contains central module of the first stage with side modules of the first stage and central unit of the second stage with side modules of the second stage, side modules are connected to central connecting rods having the possibility of being detached; besides, all modules have a housing, hydrogen tanks inside housings and at least one rocket engine in each central module and hydrogen overflow systems from side modules to the central one; in addition, it contains nuclear reactors installed in central modules and connected via heat carrier circulation pipelines to rocket engines of side modules. Additional side modules containing housings, oxidiser and fuel tanks and liquid-propellant rocket engines are connected to the above side modules. There can be used even number of side modules of the first stage, and units of roll nozzles of the first stage can be installed on two diametrically opposite side rocket modules of the first stage. There can be used odd number of side modules of the first stage, and units of roll nozzles of the first stage can be installed on all side rocket modules of the first stage. Number of side modules of the second stage can correspond to the number of side rocket units of the first stage. Number of side modules of the third stage can correspond to the number of side rocket units of the first stage. Side modules of all stages are installed in similar longitudinal planes passing through longitudinal axis of carrier rocket. Additional side modules can be attached to side modules in pairs. In nuclear rocket engine containing an expansion chamber and system for supply of heated hydrogen to it, according to the invention, hydrogen supply system includes heat exchanger to which heat carrier recirculation pipelines are connected, which in their turn are connected to nuclear reactor; hydrogen supply pipeline is connected to inlet header of expansion chamber; outlet header of expansion chamber is connected to inlet hydrogen connection pipe on heat exchanger; outlet hydrogen connection pipe is connected to gas passage and then to expansion chamber.
EFFECT: increasing the speed and flight range; improving flight safety and thrust vector control.
